The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope launched on 25 December 2021. It is a joint project between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). The primary scientific objectives of the JWST include studying the early universe, galaxy formation and evolution, and the formation of stars and planetary systems. The telescope is also used to study the atmospheres of exoplanets to search for signs of life. The JWST is positioned at the second Lagrange point (L2) of the Earth-Sun system, located about 1.5 million km (930,000 mi) away from Earth, and uses a 6.5-meter primary mirror to collect and focus infrared light from the most distant objects in the universe.

James Webb Space Telescope Distance from Earth
The distance of James Webb Space Telescope from Earth is currently 1,718,204 kilometers, equivalent to 0.011485 Astronomical Units. Light takes 5.7313 seconds to travel from James Webb Space Telescope and arrive to us.
The following chart shows the distance of James Webb Space Telescope from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of James Webb Space Telescope from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of James Webb Space Telescope to Earth
